Men's Gel Cumulus 26 - NWT - Size US 11 White

Hi - these are marked as US size 11, and also have a tag attached, so based on lack of wear and the tag, I am assuming them to be new. The only flaw I can locate is that the toe of one has a light mark. I can't identify what the mark is. I tried to remove it, but could only lighten it some. It's featured in the last shoe photo to the right of my thumb.
